It's going to be a while before the pop up happens for me, and in the mean time, with the truck starting to come back together and get prepped to go, I am looking for a way to get AC into the truck topper. The problem is my truck has a 6.5 foot bed, so a short queen mattress barely fits. My thought process, for better or worse has me looking at a little tent of sorts that covers the open end of the truck if I were to leave the truck cap hatch open, and the tailgate down. There is only one commercially available unit, the DAC Full Size truck tent, but it really doesn't facilitate the AC well. I am considering rigging something using a silver Harbor Freight tarp, gorilla tape, probably some shoe goo adhesive, velcro to close the door flap, and bungee cords. I am thinking I should be able to rig something that will allow me to hold the AC up so that it blows across the bed instead of the storage under the bed. The Arctic King 5K BTU mechanical AC from Walmart is super inexpensive, and super small, plus the 5K BTU rating should be WAY more cooling than the space requires. So my next steps are... #1. Finish the build of the new engine, install, and verify everything is good... #2. Finish stripping and repainting the used Leer 122 truck topper. Change the locks so I have a good lock that only I have a key to. #3. Finish the bed platform build. #4. Make the truck end tent. #5. Load up. #6. Gas up. #7. Head out for the maiden voyage. Most likely Crystal Beach. Good place to test. Far enough to be a fun trip, close enough to be able to run home should something with the rig go bad.
